Radio Modems - Setting the Standard
The RM96XX series of radio modems take the doubt out of the use of radio data communications in
industrial applications. RDT have been producing modems since
the 1980’s and the RM96XX series
is recognised by the world's leading control equipment manufacturers as one
of the best available. This enviable position has been reached not
only by producing the highest performance and most flexible product, but also providing
the reliability of supply and technical backup that adds to trouble free
system integration.
Internationally approved
RDT has extensive and constantly expanding international representation and
existing product type approvals throughout Europe and
many other countries. The design of the RM96XX series makes it a simple matter to
tailor the product to local regulatory requirements throughout the world. See
technical details section for full list of approvals.
Feature packed ... but simple
We make life simple for our users. Here are just some of the features
selected by simple switch settings - no special software or PC's required.
- Operating frequency, power, address
- Serial interface details - including RS232/RS485
- Forward error correction - automatic retry
- Repeater functions - including 'chain'
- AT command set - emulates telephone based modem
LED's give an instant indication of system status, received signal strength
and RS232 line status.
Applications:
Applications as diverse as air to ground links to
waste water treatment, Formula 1 motor racing to industrial SCADA, remote
control of moving plant to traffic information systems. Also telemetry, SCADA, PLC networks, variable message signs,
PTZ camera control, access
control, digitised video transmission, warehousing, building management,
traffic information and control, environmental
monitoring, robotics.

Power Amplifiers
Where local regulations permit, an RF Amplifier module may be added to
increase the output power to achieve much greater distances. RDT can
supply an amplifier with an output of 5 to 15 watts or a larger unit with
20 to 25 watts output.
The CDA series of amplifiers combine high performance with a rugged
design capable of continuous operation. The input can withstand a 100%
overdrive condition whilst the output is protected against open and short
circuits at any phase angle and remains stable under any load condition.
